The F-150 is still available as an SVT Raptor. And they're responsible for some of the higher end mustangs I believe (the Shelby GT500 specifically). The Focus ST is also part of their work. Apparently they've somewhat merged with the Europe side's RS division to make a Performance Vehicle Group.

I have to admit, an SVT Fusion does seem like a nice car, although I'm not sure I'd want to see the price. Even the regular Fusion's can get a little pricey on the upper end for what's essentially their midsize car. (Course, that's also just a reflection of how cars in general have gotten more expensive.)
